IMPROVEMENT IN HAY-ELEVATORS.

Specification forming part of Letters Patent No. 148,009, dated February 24, 1R74;y application t'llld January 16, 1874.

To all whom it may concern:

Be it known that I, Gnannrr VAN SrcKLE, of Shortsville, in the county of Ontario and State of New York, have invented a new and useful Improvement in Hay-Elevators, and I do hereby declare the following to be a full and accurate description of the same, suiicient to enable those skilled in the art to which it a-ppertains to construct and make use of the same, reference being had to the drawings accompanying this specication, and to the iigures and letters of reference marked thereon, Ain which like letters refer to like parts throughout the same.

Figure l is a central vertical view of my improvement. Fig. 2 is a side elevation of the same. Fig. 3 is a plan of the car and the track.

My improvement relates to hay-elevators. The object of my improvement is to raise hay from a wagon or floor below to any desired point above, and, after it is so raised, to transfer it horizontally to any point preferred, in a cheaper and moreA expeditious manner than has been done heretofore. It consists in coupling a four-wheel car in a manner that, when put upon a track, a portion of the couplingframe extends far enough below the coupling to attach a pulley to the extension, upon the external a-ngles of which (the periphery having been hollowed out for the rope) are ratchetteeth for pawls, for holding the pulley at any desired point in ascending or descending, outside of which pulley, and balanced on its axle, are detent-levers for holding the car in position when being loaded; an extension of the coupling-frame, attached to which, and suspended therefrom by rigid connections, is a ring, by which the levers are thrown out of detention; an incline plane attached to the side bars of the track, in contact with which, as the car passes into position to be loaded, is brought a bar, transversely attached to the front end of the tongue T, which passes up the incline and releases the rope r, held on the pulley by the brake formed of the front end of the tongue.

A A, Fig. 3, form the sides, and A the end,

of the track for my improvement, which may be extended to any desired distance. W W

are the. wheels; Ya, a, the axles; C C, the female, and 'l the male part of the coupling or tongue, attached and balanced on the shaft at x --forming and constituting the car for a hay-elevator. The hounds or tongue T is extended from the coupling to t, for the purpose of forming abrake for the pulley P, that checks the pulley, over which the rope r passes,

at any desired point. At X X is the point of the coupling of the two ends of the car, the object of which coupling being to form a longitudinal lexure, by which an action is 0btained for the working of the brake t at the front end of the tongue, hereafter described. By this method of constructing the car, a transverse exure is also obtained, the result of which is that either Aof the. car-wheels may pass over obstructions, if any happen to be lying' on the track, without strain, injury, or oscillation to any other part of the car. For the purpose of facilitating this object, there is a joint in the axles X X at the center, at a a, which joint is formed by any desired method to snit the operator. From the point m, Fig. 2, on the car, the sides O C of the coupling are extended below the track to S, where they are connected by a bolt that makes and is the axle of the pulley P, which pulley is hollowed out on its periphery, so that the rope r will fit the same. a a are ratchet-teeth in the angles of the periphery of the pulley, on which drop the pawls p @which hold the pulley from revolving. The pawls p p are hung, by one end of the same, on the axle X, which, as the brake t or end of the tongue falls to the pulley, drop on the ratchet-teeth, and hold the pulley in position at any point, as desired.

from the pulley to the point c, for the purpose of connecting and strengthening the couplingframe, and to form points of attachment for rods r, for the suspension of the ring R or other fixture for elevating or depressing the detent-levers L L, which are balanced on the pulley-axle S, the office of which levers is to hold the car in position, by means of the detent d, during the operation of loading the hay. The levers, being connected at the rear end, are both operated by the same movement of the ring R, which is attached to the connected end of the levers by rigid wood or metal connections, suspending the same, the object of which is, as the load ascends and comes in rlhe sides C' C of the coupling-frame are again extended e v macon contact with the ring, to throw the levers out of the detent d, and release the car. i is a wood or metal bar, the length of which is the width of the track, bent to an angle in the middle, tol have the ends the lowest when fastened on and transversely affixed to the top of the tongue at t, being tirlnly secured to the saine. By making the ends of this cross-bar the lowest, they are kept close to the incline h, and oscillation is prevented, and room is saved, as the angle passes up between the sides of the track. As the car returns after unloading, these ends of the cross-bar pass up the incline h, Fig. 2, which action raises the brake or tongue t, releasing the rope r on the pulley p, and permitting the hay-fork attached thereto to descend for anotherI load. Although the pawls p p, in dropping on the teeth on the pulley I?, retain the pulley in position, they do not prevent the rope from slipping, to do which the eouplingtongue T is extended to t, which is the brake -for the rope, the under side of which is hollowed out and corrugated. Its operation is: As the levers are thrown out of the detent d by the ascent of the load, and the car is released, the cross-bar fi slides down the incline l1., and brings the brake, with the weight ofthe apparatus and the load, to bear 011 the rope, in which the weight of the load is made to balance itself, which is retained in any desired position until run oit' and unloaded. The metal plates O, which forni the incline 7L, are rigidly secured to the side bars of the track, and on their lower edge there is a shoulder, d, for the detent-lever L. The length of the incline is assumed, being long orshort at pleasure.

In the track A, Figs. 1, 2, there is an angle, G, from which to A, Fig. l, the track is level, and from which to g it is inclined, as preferred, the object of which is to counteract the sudden start and jerk of the car caused by the elasticity of the rope in starting off with the load, which shakes the hay from the hay-fork, and to facilitate the return of the carto its position, to be again loaded.

What I claim, and desire to secure by Letters Patent, is-

l. The combination of the cross-joint, forniing the longitudinal flexure at x, frame C C, extended to S and c, and tongue T, extended to t, for the purposes substantially as shown and described.

2. The combination ot' the tongue T, extended to r, brake t, cross-bar z', and incline h, for the purposes substantially as described.

3. The combination of the joint a in the axles a, forming the transverse tlexure, axles a, wheels NV, and angle G, arranged substantially as and for the purpose speciiied.

4. The combination ot' the track A, angle G, wheels W, axles a., franie C C T, brake t, pawls p p, pulley I), levers L, detent d, incline h, cross-bar i, and suspended ring R, as and for the purposes substantially as shown and described. l

To which I herewith set my hand, in the presence of these two witnesses, this 6th day of January, 1874.
